200 ton tension hydraulic jack for construction is a universal pre-stressed jack used for tensioning operations of various steel strand anchors. It is widely used in post-tensioning of large buildings, structures, prestressed concrete bridges, rock anchors, hydraulic structures, foundation anchors and other major projects. 200 ton tension hydraulic jack for construction is mainly made of high-strength steel, which has the characteristics of compact structure, light weight and small volume. The axial length is short, and the remaining stretched length of the steel strand is short, which can save the material of the steel strand. It is flexible installation, durable, easy to operate, and convenient to maintain.
The working principle of 200 ton tension hydraulic jack for construction: when tensioning the prestressed tendons, the oil nozzle of the tensioning cylinder enters the oil, the oil nozzle of the upper pressure cylinder returns oil, and the upper pressure oil cylinder, the connecting sleeve and the supporting sleeve are connected together to move the fixed ring to the right; The hydraulic cylinder, the end cap nut, the plug and the core sleeve are connected as a whole, and the tool anchor is driven to move to the left to tension the prestressed tendons. When anchoring the top pressure, the nozzle of the top pressure cylinder enters the oil under the condition of maintaining tension. The top pressure, the protective sleeve and the top pressure head are integrally connected and move to the right to push the clamp into the anchor ring; at this time, the nozzle of the tensioning cylinder returns The oil enters the nozzle of the top pressure cylinder, and the tension cylinder returns by hydraulic pressure. The nozzle of the tension cylinder and the nozzle of the top pressure cylinder return oil at the same time, and the top pressure returns to the return stroke under the action of elastic force. For long-span structures, longer wiring harnesses and other larger extensions, it is recommended to use straight-through jacks. Prestressed anchors (round anchors, flat anchors and anchors) are anchors that are installed at the end of the steel strand and can be stretched.
1. The hydraulic cylinder is connected to the oil pump through the high-pressure oil pipe, and the professional electrician connects the oil pump to the power source through the power cord.
2. Turn on the oil pump and make it run no less than 3 times. If the power is off, stop the pump to check and analyze the cause. Before calibrating the tension jack and the oil pump system, the jack must be in operation. After everything is normal, you can enter calibration or tensioning work.
